1 Introduction

Welcome to Z/IPStream X/2 and 9X/2, the new ﬂagship streaming software encoders from The Telos Alliance.

Built on the Omnia A/XE platform, Z/IPStream encoders add revolutionary new features designed for the modern

and future needs of audio encoding. One such feature is Z/IPStream X/2’s Adaptive streaming, which allows for

media players to automatically adapt to changing network conditions. Z/IPStream X/2 encodes the same stream

at multiple bitrates, and keeps the audio packets sample-aligned to enable media players to seamlessly switch

between bitrates. Adaptive streaming supports both Microsoft’s Smooth Streaming and Apple’s HLS formats.

In addition to the included Omnia 3-band audio processor, Z/IPStream X/2 can add optional Omnia 9 audio

processing, complete with exclusive “Undo” technology and 6band parametric EQ. The 3-band audio processing

can provide value when stream density is of primary importance. When purchased along with the Omnia 9 audio

processing option, the product is called Z/IPStream 9X/2.

This document describes both Z/IPStream X/2 and 9X/2 version. To avoid repetition, we’re going to refer to Z/

IPStream X/2 throughout the text, but the content is equally applicable to both X/2 and 9X/2. Chapter 8 is the only

one that applies only to Z/IPStream 9X/2.

Another important feature is audio spot replacement. Spot replacement allows restricted streaming material to

be replaced with content from either another source or audio files. In addition to email notifications, SNMP

alarms are particularly valuable for large deployments, and can instantly detect and inform you of problems

with your streams.

Z/IPStream X/2 is also cloud-ready, and can be easily monitored and conﬁgured remotely from PC’s, Macs, tablets

and smart phones. In addition to the HTML5 web interface, X/2 implements a REST-style API for programmatic

control, perfect for conﬁguration, monitoring, or dynamic control from a variety of third-party tools and

programming languages.

On the encoding side, Z/IPStream X/2 supports: MPEG Layer III (MP3), Low Complexity Advanced Audio

Coding (AAC-LC), High Eﬃciency AAC (HE-AAC), and HE-AAC v2 (also called AAC-Plus). Z/IPStream X/2 is

designed to run as a Windows service for 24/7 operation.

Our Omnia processors dominate the airwaves and streams across the globe. The products that have helped us

achieve this level of success are based upon innovative ideas in dynamics audio processing and, together with

encoding and stream management, Z/IPStream X/2 brings these ideas to your PC.

Audio processing for AM/FM broadcast has been around for decades, and is a well-understood science. Today, the

real excitement surrounds audio streams over mobile devices. Some of the transport methods may be diﬀerent, but

the need for quality audio processing is just as important.

Eﬀective audio processing is the “secret weapon” in taking your mobile or internet streams from sounding okay,

to sounding great. The perceived quality of bitrate compressed audio is vastly improved with the addition of

dynamics processing.

These are just a few of the reasons why Z/IPStream X/2 is so relevant for today, and more than ready for tomorrow.

This manual will walk you through the installation, setup and operation of Z/IPStream X/2. And, since audio

processing is as much an art as a science, it will help you to develop an audio processing philosophy that will

complement your format. You will also gain an understanding of what’s happening to your audio signal as it travels

from the input connectors to the streaming ports.

INTRODUCTION

Software Installation

Z/IPStream X/2 requires Windows 7, or later. It is delivered as a single installer ﬁle named Z/IPStreamx2.msi.

Since the installer will conﬁgure the Z/IPStream X/2 to run as a Windows Service, make sure to be logged in with

Administrative privileges before starting the installation process. To begin, double-click the Z/IPStreamx2.msi ﬁle.

Answer a few prompts and the installer will guide you through the installation process.

Application Overview

After Z/IPStream X/2 is installed, it runs as a Windows service. The beneﬁt of running as a service is improved

security and reliability; a user does not need to be logged on, as long as Windows is running, Z/IPStream X/2 is also

running in the background. This also means that the application is not immediately visible. Instead, conﬁguration

and management is handled through an Internet browser (i.e. Internet Explorer, Firefox, Google Chrome, Opera

etc.). Although you may conﬁgure Z/IPStream X/2 from any computer that can reach the Z/IPStream PC over the

network, we recommend performing the initial conﬁguration from the same PC.

The installer will add Windows Firewall exception rules. If the Z/IPStream PC has an active third-party ﬁrewall

you must conﬁgure the ﬁrewall to allow Z/IPStream to talk to the network. To reconﬁgure Windows Firewall

please take a look at the Firewall Setup chapter for details on how to add Z/IPStream to the ﬁrewall’s exception

list. During the initial application setup, it may be helpful to temporarily disable the ﬁrewall until you are able to

connect to Z/IPStream.

Service Management

Since Z/IPStream X/2 is always running in the background, there may be times that you need to shut it down or

restart it. This is accomplished through the Service manager control panel applet. The Managing Z/IPStream

Service chapter describes how to accomplish this task.

SECTION 2

Initial Conguration

The steps involved in conﬁguring Z/IPStream X/2 are:

♦ Connect to Z/IPStream X/2 with a web browser

♦ Change the default password

♦ Enter your license information

♦ Deﬁne audio sources

♦ Create audio processing and encode instances

Each step is described in a separate section, below.

Connecting to Z/IPStream X/2 with a Web Browser

By default, Z/IPStream X/2 will use HTTP port 80 for administration. If this port is in use by another application,

Z/IPStream X/2 will select the next available port, counting up. For this reason, we recommend that the ﬁrst time

you connect to Z/IPStream X/2, do so on the same PC where the program is installed.

Select the Conﬁgure Z/IPStream X/2 shortcut from the Z/IPStream X/2 program shortcuts. This will open

your default browser application to connect to Z/IPStream. This shortcut is aware of the port that is used by Z/

IPStream, and will pass this information on to the browser.

1. You should see the following login page appear on your browser:

Enter “user” (case sensitive) as the user name and leave the password ﬁeld blank. Next, click the Submit button.

SECTION 2

| 4

INITIAL CONFIGURATION

2. Next, you will see the main control panel: this is where all audio processing and encoding instances are

displayed. Initially, this page will not show any instances.

You are now logged in to Z/IPStream X/2.

Change the Default Password (and Global Options)

One of the ﬁrst things to do is change the default password. Leaving it unchanged could give hackers easy access to

your Z/IPStream X/2 application.

1. Click the Options link in the top part of the Control Panel window:

SECTION 2

| 5

INITIAL CONFIGURATION

2. The Options window will now be displayed:

3. Change the Administrative password ﬁeld to a password of your choice, and enter it again in the repeat

password ﬁeld.

4. While you are on this page, you also have the option of changing the web interface HTTP and HTTPS ports,

and the HTTP stream server port. The default values should work ﬁne for most applications. Only change

them if you need to address a particular issue. Note however, that any changes you make to these ports will

only take eﬀect after Z/IPStream X/2 has been restarted by restarting the Z/IPStream service, or the PC.

5. The next ﬁeld sets the stream server reconnect interval. Again, the default value of 10 seconds should work

in most instances.

6. On the next ﬁeld enter the syslog server address. Also enter the number of days the log ﬁles will be saved

before they are purged. The range is from 1 to 360 days.

SECTION 2

| 6

INITIAL CONFIGURATION

7. Finally, check the Email on error box if you want the Z/IPStream application to send you e-mail

notiﬁcations. Checking this box opens the following ﬁelds:

♦ Email address for error notiﬁcation – Enter an email address in this ﬁeld. While emails may be sent

directly to e-mail recipients, they can also be sent as text messages to mobile phones. If you are not

familiar with how to do this, see the tutorial at http://sms411.net/how-to-send-email-to-a-phone/.

♦ Sender name – The default is ‘Z/IPStream X/2 application’. It will be useful to change this, if you have

more than one Z/IPStream X/2 running in your facility).

♦ Sender email address –enter the account username.

♦ SMTP server address – You may enter either an IP address in the ###.###.###.### numeric format, or a

name address (e.g. smtp.gmail.com). In order to resolve the name address, a working DNS server must

be already conﬁgured on the PC.

♦ SMTP server port – The default is 25, but you may change it if necessary.

♦ Use SSL connection – Checking this box will ensure that your SMTP communications are encrypted and

secure from hackers but it will work only if your email service provider can accept SSL connections.

♦ Email send interval – Determines how frequently Z/IPStream sends you email alerts about a problem.

The default is 3600 seconds (one hour). We suggest not setting it lower. You want to have a value large

enough to give you enough time to resolve the situation before the problem repeats. Otherwise, in case of

a persistent problem, you may end up having your email ﬂooded with too many messages.

♦ SMTP username – Enter user name here.

♦ SMTP password – Enter password here.

Click the Save button to make the changes permanent. You will then be returned to the Control Panel page.

SECTION 2

INITIAL CONFIGURATION

Enter the License Information

Before you can begin creating audio sources or encoders, you will need to enter the license code(s) that you

received with Z/IPStream X/2 on the Licenses page. The licenses determine the number of audio inputs that can be

created in the application.

NOTE:

Licenses are veried with a Telos license server. Make sure the PC is connected to the internet when

you enter the license codes.

1. Click the Licenses link at the top of the Control Panel page. The Licenses page will be displayed:

2. Click the Add… button. Enter your license code in the License ﬁeld then click the Save button

3. The code you entered will show up in the Licenses list on the left. Next to the license code you will see

additional text describing the state of the license. The text will initially say “Pending activation” then after

10-15 seconds it should change to “OK”. To reload the license status use the “Refresh” button. Repeat step

2 for each license code you have received. If all license codes have an “OK” status then skip step 4 below and

jump to the Create Audio Sources section.

4. If you see an error message next to the license code, please check the license string to make sure it matches

the one you received. If the error is “Activation failed”, or similar, then contact customer support at

+1 (216) 622-0247 or [email protected] to learn how to activate your license manually.

SECTION 3

Dene Audio Sources

Now that you’ve got the licensing taken care of, the next step is to deﬁne your audio sources.

The Audio Sources page allows you to select the input audio device(s) you wish to use with Z/IPStream X/2. Since the

Windows audio device names are often not very descriptive, we give you the opportunity to assign each audio device a

friendly name. This name is then used throughout the rest of the application to refer to the audio source. You may also

deﬁne Axia Liv`ewire and RTP audio sources.

NOTE:

You will only be able to create audio sources once you have successfully activated your license code(s).

The number of audio sources you may dene is determined by the licenses congured.

1. On the Control Panel page, click the Audio Sources link at the top of the window. The Audio Sources page will be

displayed:

2. Click the Add...button. Select the audio device you wish to use from the Source device drop down list. You may

select between: Wave: local audio card, Livewire: network stream and RTP, local port.

9 | Section 3

SECTION 3

DEFINE AUDIO SOURCES

3. In the Add Audio Source dialog, enter a “friendly” name. Since this is the name that will appear in the rest

of the application, select a name that indicates the program content name. For Sampling rate, select the rate

you wish to use for you streams. The application will read the audio at this rate or will resample it, if needed,

to match the selected rate. Enter the source-speciﬁc parameters then click the Save button.

4. Repeat step 2 for each audio source you wish to use. You may see a message indicating that the audio device

limit has been reached for the license codes that you entered for the application. If you see this message and

still need additional audio sources, please purchase an additional license.

5. When done, click the Main menu shortcut to return to the Control Panel page.

Creating Audio Processor and

Encoding Instances

Now that you have deﬁned Z/IPStream’s audio sources, the next step is to create audio processor instances or

encoders. On the main Control Panel, click on the +New button. You will be presented with the following options:

From here, decide if you want to create an audio processing instance, or an AAC, MP3 or Adaptive AAC encoder instance.

CREATING AUDIO PROCESSOR AND ENCODING INSTANCES

Creating an Audio Processor Instance

The Audio Processor instance takes its input from one of the audio sources that you deﬁned in the previous section,

processes it, then sends it along to an audio output device. That device can be a sound card installed in the PC, a

Virtual Audio Cable or an Axia IP-Audio device.

To create an audio processor instance, make your selections from the following ﬁelds and click Save.

♦ Name – Give your audio processor an easily identiﬁable name.

♦ Audio source - Select an audio source. The audio sources you created earlier will appear in the dropdown list.

♦ Processing – Select between none, Omnia 3, or, if you have purchased the option, Omnia 9. Refer to later

chapters about adjusting the audio processing options oﬀered by the two audio processors.

♦ Processing preset – If you have select Omnia 3 as the audio processor, you may select a processing preset

here. Due to the full range of audio processing tools, the Omnia 9 management is done using a separate

application called NfRemote. Refer to Chapter 8 for more information.

♦ Output device – Select the desired audio output device, here.

♦ Sync buﬀer (seconds, and samples) – We suggest keeping these setting at default values, unless instruct-

ed otherwise by tech support. The parameters control the synchronization algorithm between input and

output devices. While it is always best to use the same audio card for input and output, sometimes this is

not possible. Diﬀerent audio cards have slightly diﬀerent sample clocks from each other. In order to avoid

buﬀer underﬂow/overﬂow problems, Z/IPStream’s synchronization algorithm adjusts the playout rate to

match the source input.

Once you’re done with the processor settings, take a moment to run some test audio through it, just to make sure

you see audio on the input and output meters. This conﬁrms that you’ve done everything right with setting up the

audio sources and processor.

CREATING AUDIO PROCESSOR AND ENCODING INSTANCES

AAC Standard Encoder

Z/IPStream’s AAC Standard Encoder instance accepts audio from a source, encodes it to AAC, and then passes the

encoded stream along to one or more servers that you specify. Remember that that the encoded stream can be sent

simultaneously to multiple servers, which will then replicate the stream to the client.

To create an AAC standard encoder instance, make your selections from the following ﬁelds and click Save.

♦ Name – Give your AAC encoder an easily identiﬁable name.

♦ Audio source - Select an audio source from the list that you created at the beginning of this section.

♦ Processing – Select between none, Omnia 3, or, if you have purchased the option, Omnia 9. Refer to later

chapters about adjusting the audio processing options oﬀered by the two audio processors.

♦ Processing preset – If you have select Omnia 3 as the audio processor, you may select a processing preset

here. Due to the full range of audio processing tools, the Omnia 9 management is done using a separate

application called NfRemote. Refer to Chapter 8 for more information.

♦ AAC format –In addition to the basic AAC format, several extensions have been added, and you need to

choose between:

 AAC – the basic AAC format

 HE-AAC - High Eﬃciency Advanced Audio Coding. It is for bitrates between 24 – 96 kb/s.

 HE-AAC v2 - High Eﬃciency Advanced Audio Coding version 2 is an improved variant of HE-AAC

that will enhance the compression eﬃciency of stereo signals. It is for lower bitrates between 14 – 56

kb/s. Please note that while HE-AAC v2 is widely supported, it may not work on all players. Next, use

the dropdown menu to select Mono or Stereo
